+The files @file{nn*.el} provide functionality for accessing NNTP
+(@file{nntp.el}), IMAP (@file{nnimap.el}) and several other Mail back
+ends (probably @file{nnml.el}, @file{nnfolder.el} and
+@file{nnmaildir.el} are the most widely used mail back ends).

+@node Gnus Maintainance Guide
+@chapter Gnus Maintainance Guide
+
+@section Stable and development versions
+
+The development of Gnus normally is done on the CVS trunk, i.e. there
+are no separate branches to develop and test new features.  Most of the
+time, the trunk is developed quite actively with more or less daily
+changes.  Only after a new major release, e.g. 5.10.1, there's usually a
+feature period of several months.  After the release of Gnus 5.10.6 the
+development of new features started again on the trunk while the 5.10
+series is continued on the stable branch (v5-10) from which more stable
+releases will be done when needed (5.10.7, @dots{}).
+@ref{Gnus Development, ,Gnus Development, gnus, The Gnus Newsreader}
+
+Stable releases of Gnus finally become part of Emacs.  E.g. Gnus 5.8
+became a part of Emacs 21 (relabeled to Gnus 5.9).  The 5.10 series 
+became part of Emacs 22 as Gnus 5.11.
+
+@section Syncing
+
+@c Some MIDs related to this follow.  Use http://thread.gmane.org/MID
+@c (and click on the subject) to get the thread on Gmane.
+
+@c Some quotes from Miles Bader follow...
+
+@c <v9eklyke6b.fsf@marauder.physik.uni-ulm.de>
+@c <buovfd71nkk.fsf@mctpc71.ucom.lsi.nec.co.jp>
+
+In the past, the inclusion of Gnus into Emacs was quite cumbersome.  For
+each change made to Gnus in Emacs repository, it had to be checked that
+it was applied to the new Gnus version, too.  Else, bug fixes done in
+Emacs repository might have been lost.
+
+With the inclusion of Gnus 5.10, Miles Bader has set up an Emacs-Gnus
+gateway to ensure the bug fixes from Emacs CVS are propagated to Gnus
+CVS semi-automatically.  These bug fixes are installed on the stable
+branch and on the trunk.  Basically the idea is that the gateway will
+cause all common files in Emacs and Gnus v5-10 to be identical except
+when there's a very good reason (e.g., the Gnus version string in Emacs
+says @samp{5.11}, but the v5-10 version string remains @samp{5.10.x}).
+Furthermore, all changes in these files in either Emacs or the v5-10
+branch will be installed into the Gnus CVS trunk, again except where
+there's a good reason.
+@c (typically so far the only exception has been that the changes
+@c already exist in the trunk in modified form).
+Because of this, when the next major version of Gnus will be included in
+Emacs, it should be very easy -- just plonk in the files from the Gnus
+trunk without worrying about lost changes from the Emacs tree.
+
+The effect of this is that as hacker, you should generally only have to
+make changes in one place:
+
+@itemize
+@item
+If it's a file which is thought of as being outside of Gnus (e.g., the
+new @file{encrypt.el}), you should probably make the change in the Emacs
+tree, and it will show up in the Gnus tree a few days later.
+
+If you don't have Emacs CVS access (or it's inconvenient), you can
+change such a file in the v5-10 branch, and it should propagate to Emacs
+CVS -- however, it will get some extra scrutiny (by Miles) to see if the
+changes are possibly controversial and need discussion on the mailing
+list.  Many changes are obvious bug-fixes however, so often there won't
+be any problem.
+
+@item
+If it's to a Gnus file, and it's important enough that it should be part
+of Emacs and the v5-10 branch, then you can make the change on the v5-10
+branch, and it will go into Emacs CVS and the Gnus CVS trunk (a few days
+later).  The most prominent examples for such changes are bug-fixed
+including improvements on the documentation.
+
+If you know that there will be conflicts (perhaps because the affected
+source code is different in v5-10 and the Gnus CVS trunk), then you can
+install your change in both places, and when I try to sync them, there
+will be a conflict -- however, since in most such cases there would be a
+conflict @emph{anyway}, it's often easier for me to resolve it simply if
+I see two @samp{identical} changes, and can just choose the proper one,
+rather than having to actually fix the code.
+
+@item
+For general Gnus development changes, of course you just make the
+change on the Gnus CVS trunk and it goes into Emacs a few years
+later... :-)
+@end itemize
+
+Of course in any case, if you just can't wait for me to sync your
+change, you can commit it in more than one place and probably there will
+be no problem; usually the changes are textually identical anyway, so
+can be easily resolved automatically (sometimes I notice silly things in
+such multiple commits, like whitespace differences, and unify those ;-).
+
+
+@c I do Emacs->Gnus less often (than Gnus->Emacs) because it tends to
+@c require more manual work.
+
+@c By default I sync about once a week.  I also try to follow any Gnus
+@c threads on the mailing lists and make sure any changes being discussed
+@c are kept more up-to-date (so say 1-2 days delay for "topical" changes).
+
+@c <buovfd71nkk.fsf@mctpc71.ucom.lsi.nec.co.jp>
+
+@c BTW, just to add even more verbose explanation about the syncing thing:

+@c This file contains a list of news features Gnus.  It is supposed to be
+@c included in `gnus.texi'.  `GNUS-NEWS' is automatically generated from
+@c this file (see `gnus-news.el').
+
+@itemize @bullet
+
+@item Installation changes
+
+@itemize @bullet
+@item Upgrading from previous (stable) version if you have used No Gnus.
+
+If you have tried No Gnus (the unstable Gnus branch leading to this
+release) but went back to a stable version, be careful when upgrading
+to this version.  In particular, you will probably want to remove the
+@file{~/News/marks} directory (perhaps selectively), so that flags are
+read from your @file{~/.newsrc.eld} instead of from the stale marks
+file, where this release will store flags for nntp.  See a later entry
+for more information about nntp marks.  Note that downgrading isn't
+safe in general.
+
+@item Lisp files are now installed in @file{.../site-lisp/gnus/} by default.
+It defaulted to @file{.../site-lisp/} formerly.  In addition to this,
+the new installer issues a warning if other Gnus installations which
+will shadow the latest one are detected.  You can then remove those
+shadows manually or remove them using @code{make
+remove-installed-shadows}.
+@end itemize
+
+@item New packages and libraries within Gnus
+
+@itemize @bullet
+
+@item Gnus includes the Emacs Lisp @acronym{SASL} library.
+
+This provides a clean @acronym{API} to @acronym{SASL} mechanisms from
+within Emacs.  The user visible aspects of this, compared to the earlier
+situation, include support for @acronym{DIGEST}-@acronym{MD5} and
+@acronym{NTLM}.   @xref{Top, ,Emacs SASL, sasl, Emacs SASL}.
+
+@item ManageSieve connections uses the @acronym{SASL} library by default.
+
+The primary change this brings is support for @acronym{DIGEST-MD5} and
+@acronym{NTLM}, when the server supports it.
+
+@item Gnus includes a password cache mechanism in password.el.
+
+It is enabled by default (see @code{password-cache}), with a short
+timeout of 16 seconds (see @code{password-cache-expiry}).  If
+@acronym{PGG} is used as the @acronym{PGP} back end, the @acronym{PGP}
+passphrase is managed by this mechanism.  Passwords for ManageSieve
+connections are managed by this mechanism, after querying the user
+about whether to do so.
+@end itemize
+
+@item Changes in summary and article mode
+
+@itemize @bullet
+
+@item Gnus now supports sticky article buffers.  Those are article buffers
+that are not reused when you select another article.  @xref{Sticky
+Articles}.
+
+@item International host names (@acronym{IDNA}) can now be decoded
+inside article bodies using @kbd{W i}
+(@code{gnus-summary-idna-message}).  This requires that GNU Libidn
+(@url{http://www.gnu.org/software/libidn/}) has been installed.
+@c FIXME: Also mention @code{message-use-idna}?
+
+@item The non-@acronym{ASCII} group names handling has been much
+improved.  The back ends that fully support non-@acronym{ASCII} group
+names are now @code{nntp}, @code{nnml}, and @code{nnrss}.  Also the
+agent, the cache, and the marks features work with those back ends.
+@xref{Non-ASCII Group Names}.
+
+@item Gnus now displays @acronym{DNS} master files sent as text/dns
+using dns-mode.
+
+@item Gnus supports new limiting commands in the Summary buffer:
+@kbd{/ r} (@code{gnus-summary-limit-to-replied}) and @kbd{/ R}
+(@code{gnus-summary-limit-to-recipient}).  @xref{Limiting}.
+
+@item You can now fetch all ticked articles from the server using
+@kbd{Y t} (@code{gnus-summary-insert-ticked-articles}).  @xref{Summary
+Generation Commands}.
+
+@item Gnus supports a new sort command in the Summary buffer:
+@kbd{C-c C-s C-t} (@code{gnus-summary-sort-by-recipient}).  @xref{Summary
+Sorting}.
+
+@item @acronym{S/MIME} now features @acronym{LDAP} user certificate searches.
+You need to configure the server in @code{smime-ldap-host-list}.
+
+@item URLs inside Open@acronym{PGP} headers are retrieved and imported
+to your PGP key ring when you click on them.
+
+@item
+Picons can be displayed right from the textual address, see
+@code{gnus-picon-style}.  @xref{Picons}.
+
+@item @acronym{ANSI} @acronym{SGR} control sequences can be transformed
+using @kbd{W A}.
+
+@acronym{ANSI} sequences are used in some Chinese hierarchies for
+highlighting articles (@code{gnus-article-treat-ansi-sequences}).
+
+@item Gnus now MIME decodes articles even when they lack "MIME-Version" header.
+This changes the default of @code{gnus-article-loose-mime}.
+
+@item @code{gnus-decay-scores} can be a regexp matching score files.
+For example, set it to @samp{\\.ADAPT\\'} and only adaptive score files
+will be decayed.  @xref{Score Decays}.
+
+@item Strings prefixing to the @code{To} and @code{Newsgroup} headers in
+summary lines when using @code{gnus-ignored-from-addresses} can be
+customized with @code{gnus-summary-to-prefix} and
+@code{gnus-summary-newsgroup-prefix}.  @xref{To From Newsgroups}.
+
+@item You can replace @acronym{MIME} parts with external bodies.
+See @code{gnus-mime-replace-part} and @code{gnus-article-replace-part}.
+@xref{MIME Commands}, @ref{Using MIME}.
+
+@item
+The option @code{mm-fill-flowed} can be used to disable treatment of
+format=flowed messages.  Also, flowed text is disabled when sending
+inline @acronym{PGP} signed messages.  @xref{Flowed text, ,Flowed text,
+emacs-mime, The Emacs MIME Manual}.  (New in Gnus 5.10.7)
+@c This entry is also present in the node "Oort Gnus".
+
+@end itemize
+
+@item Changes in Message mode
+
+@itemize @bullet
+@item Gnus now supports the ``hashcash'' client puzzle anti-spam mechanism.
+Use @code{(setq message-generate-hashcash t)} to enable.
+@xref{Hashcash}.
+
+@item You can now drag and drop attachments to the Message buffer.
+See @code{mml-dnd-protocol-alist} and @code{mml-dnd-attach-options}.
+@xref{MIME, ,MIME, message, Message Manual}.
+
+@item The option @code{message-yank-empty-prefix} now controls how
+empty lines are prefixed in cited text.  @xref{Insertion Variables,
+,Insertion Variables, message, Message Manual}.
+
+@item Gnus uses narrowing to hide headers in Message buffers.
+The @code{References} header is hidden by default.  To make all
+headers visible, use @code{(setq message-hidden-headers nil)}.
+@xref{Message Headers, ,Message Headers, message, Message Manual}.
+
+@item You can highlight different levels of citations like in the
+article buffer.  See @code{gnus-message-highlight-citation}.
+
+@item @code{auto-fill-mode} is enabled by default in Message mode.
+See @code{message-fill-column}.  @xref{Various Message Variables, ,
+Message Headers, message, Message Manual}.
+
+@item You can now store signature files in a special directory
+named @code{message-signature-directory}.
+
+@item The option @code{message-citation-line-format} controls the format
+of the "Whomever writes:" line.  You need to set
+@code{message-citation-line-function} to
+@code{message-insert-formated-citation-line} as well.
+@end itemize
+
+@item Changes in back ends
+
+@itemize @bullet
+@item The nntp back end stores article marks in @file{~/News/marks}.
+
+The directory can be changed using the (customizable) variable
+@code{nntp-marks-directory}, and marks can be disabled using the
+(back end) variable @code{nntp-marks-is-evil}.  The advantage of this
+is that you can copy @file{~/News/marks} (using rsync, scp or
+whatever) to another Gnus installation, and it will realize what
+articles you have read and marked.  The data in @file{~/News/marks}
+has priority over the same data in @file{~/.newsrc.eld}.
+
+@item
+You can import and export your @acronym{RSS} subscriptions from
+@acronym{OPML} files.  @xref{RSS}.
+
+@item @acronym{IMAP} identity (@acronym{RFC} 2971) is supported.
+
+By default, Gnus does not send any information about itself, but you can
+customize it using the variable @code{nnimap-id}.
+
+@item The @code{nnrss} back end now supports multilingual text.
+Non-@acronym{ASCII} group names for the @code{nnrss} groups are also
+supported.  @xref{RSS}.
+
+@item Retrieving mail with @acronym{POP3} is supported over @acronym{SSL}/@acronym{TLS} and with StartTLS.
+
+@item The nnml back end allows other compression programs beside @file{gzip}
+for compressed message files.  @xref{Mail Spool}.
+
+@item The nnml back end supports group compaction.
+
+This feature, accessible via the functions
+@code{gnus-group-compact-group} (@kbd{G z} in the group buffer) and
+@code{gnus-server-compact-server} (@kbd{z} in the server buffer)
+renumbers all articles in a group, starting from 1 and removing gaps.
+As a consequence, you get a correct total article count (until
+messages are deleted again).
+@end itemize
+
+@item Appearance
+@c Maybe it's not worth to separate this from "Miscellaneous"?
+
+@itemize @bullet
+
+@item The tool bar has been updated to use GNOME icons.
+You can also customize the tool bar.  There's no documentation in the
+manual yet, but @kbd{M-x customize-apropos RET -tool-bar$} should get
+you started.  (Only for Emacs, not in XEmacs.)
+@c FIXME: Document this in the manual
+
+@item The tool bar icons are now (de)activated correctly
+in the group buffer, see the variable @code{gnus-group-update-tool-bar}.
+Its default value depends on your Emacs version.
+@c FIXME: Document this in the manual
+
+@item You can change the location of XEmacs' toolbars in Gnus buffers.
+See @code{gnus-use-toolbar} and @code{message-use-toolbar}.
+
+@end itemize
+
+@item Miscellaneous changes
+
+@itemize @bullet
+@item Having edited the select-method for the foreign server in the
+server buffer is immediately reflected to the subscription of the groups
+which use the server in question.  For instance, if you change
+@code{nntp-via-address} into @samp{bar.example.com} from
+@samp{foo.example.com}, Gnus will connect to the news host by way of the
+intermediate host @samp{bar.example.com} from next time.
+
+@item The @file{all.SCORE} file can be edited from the group buffer
+using @kbd{W e}.

+@node Non-ASCII Group Names
+@section Accessing groups of non-English names
+@cindex non-ascii group names
+
+There are some news servers that provide groups of which the names are
+expressed with their native languages in the world.  For instance, in a
+certain news server there are some newsgroups of which the names are
+spelled in Chinese, where people are talking in Chinese.  You can, of
+course, subscribe to such news groups using Gnus.  Currently Gnus
+supports non-@acronym{ASCII} group names not only with the @code{nntp}
+back end but also with the @code{nnml} back end and the @code{nnrss}
+back end.
+
+Every such group name is encoded by a certain charset in the server
+side (in an @acronym{NNTP} server its administrator determines the
+charset, but for groups in the other back ends it is determined by you).
+Gnus has to display the decoded ones for you in the group buffer and the
+article buffer, and needs to use the encoded ones when communicating
+with servers.  However, Gnus doesn't know what charset is used for each
+non-@acronym{ASCII} group name.  The following two variables are just
+the ones for telling Gnus what charset should be used for each group:
+
+@table @code
+@item gnus-group-name-charset-method-alist
+@vindex gnus-group-name-charset-method-alist
+An alist of select methods and charsets.  The default value is
+@code{nil}.  The names of groups in the server specified by that select
+method are all supposed to use the corresponding charset.  For example:
+
+@lisp
+(setq gnus-group-name-charset-method-alist
+      '(((nntp "news.com.cn") . cn-gb-2312)))
+@end lisp
+
+Charsets specified for groups with this variable are preferred to the
+ones specified for the same groups with the
+@code{gnus-group-name-charset-group-alist} variable (see below).
+
+A select method can be very long, like:
+
+@lisp
+(nntp "gmane"
+      (nntp-address "news.gmane.org")
+      (nntp-end-of-line "\n")
+      (nntp-open-connection-function
+       nntp-open-via-rlogin-and-telnet)
+      (nntp-via-rlogin-command "ssh")
+      (nntp-via-rlogin-command-switches
+       ("-C" "-t" "-e" "none"))
+      (nntp-via-address @dots{}))
+@end lisp
+
+In that case, you can truncate it into @code{(nntp "gmane")} in this
+variable.  That is, it is enough to contain only the back end name and
+the server name.
+
+@item gnus-group-name-charset-group-alist
+@cindex UTF-8 group names
+@vindex gnus-group-name-charset-group-alist
+An alist of regexp of group name and the charset for group names.
+@code{((".*" . utf-8))} is the default value if UTF-8 is supported,
+otherwise the default is @code{nil}.  For example:
+
+@lisp
+(setq gnus-group-name-charset-group-alist
+      '(("\\.com\\.cn:" . cn-gb-2312)
+        (".*" . utf-8)))
+@end lisp
+
+Note that this variable is ignored if the match is made with
+@code{gnus-group-name-charset-method-alist}.
+@end table
+
+Those two variables are used also to determine the charset for encoding
+and decoding non-@acronym{ASCII} group names that are in the back ends
+other than @code{nntp}.  It means that it is you who determine it.  If
+you do nothing, the charset used for group names in those back ends will
+all be @code{utf-8} because of the last element of
+@code{gnus-group-name-charset-group-alist}.
+
+There is one more important variable for non-@acronym{ASCII} group
+names.  @emph{XEmacs users must set this}.  Emacs users necessarily need
+not do:
+
+@table @code
+@item nnmail-pathname-coding-system
+The value of this variable should be a coding system or @code{nil}
+(which is the default).  The @code{nnml} back end, the @code{nnrss} back
+end, the @acronym{NNTP} marks feature (@pxref{NNTP marks}), the agent,
+and the cache use non-@acronym{ASCII} group names in those files and
+directories.  This variable overrides the value of
+@code{file-name-coding-system} which specifies the coding system used
+when encoding and decoding those file names and directory names.
+
+In XEmacs (with the @code{mule} feature), @code{file-name-coding-system}
+is the only means to specify the coding system used to encode and decode
+file names.  Therefore, @emph{you, XEmacs users, have to set it} to the
+coding system that is suitable to encode and decode non-@acronym{ASCII}
+group names.  On the other hand, Emacs uses the value of
+@code{default-file-name-coding-system} if @code{file-name-coding-system}
+is @code{nil}.  Normally the value of
+@code{default-file-name-coding-system} is initialized according to the
+locale, so you will need to do nothing if the value is suitable to
+encode and decode non-@acronym{ASCII} group names.
+
+The value of this variable (or @code{default-file-name-coding-system})
+does not necessarily need to be the same value that is determined by
+@code{gnus-group-name-charset-method-alist} and
+@code{gnus-group-name-charset-group-alist}.
+
+If you want to subscribe to the groups spelled in Chinese but
+@code{default-file-name-coding-system} is initialized by default to
+@code{iso-latin-1} for example, that is the most typical case where you
+have to set @code{nnmail-pathname-coding-system} even if you are an
+Emacs user.  The @code{utf-8} coding system is a good candidate for it.
+Otherwise, you may change the locale in your system so that
+@code{default-file-name-coding-system} may be initialized to an
+appropriate value, instead of specifying this variable.
+@end table
+
+Note that when you copy or move articles from a non-@acronym{ASCII}
+group to another group, the charset used to encode and decode group
+names should be the same in both groups.  Otherwise the Newsgroups
+header will be displayed incorrectly in the article buffer.

+Gnus stores marks (@pxref{Marking Articles}) for @acronym{NNTP}

+in a group and each file is specific to the corresponding server.
+Marks files are stored in @file{~/News/marks}
+(@code{nntp-marks-directory}) under a classic hierarchy resembling
+that of a news server, for example marks for the group
+@samp{gmane.discuss} on the news.gmane.org server will be stored in
+the file @file{~/News/marks/news.gmane.org/gmane/discuss/.marks}.
+
+Marks files are useful because you can copy the @file{~/News/marks}
+directory (using rsync, scp or whatever) to another Gnus installation,
+and it will realize what articles you have read and marked.  The data
+in @file{~/News/marks} has priority over the same data in
+@file{~/.newsrc.eld}.
+
+Note that marks files are very much server-specific: Gnus remembers
+the article numbers so if you don't use the same servers on both
+installations things are most likely to break (most @acronym{NNTP}
+servers do not use the same article numbers as any other server).
+However, if you use servers A, B, C on one installation and servers A,
+D, E on the other, you can sync the marks files for A and then you'll
+get synchronization for that server between the two installations.
+
+Using @acronym{NNTP} marks can possibly incur a performance penalty so

+This standard is documented in RFC2222.  It provides a simple method for
+adding authentication support to various application protocols.
+
+The toplevel interface of this library is inspired by Java @sc{sasl}
+Application Program Interface.  It defines an abstraction over a series
+of authentication mechanism drivers (@ref{Back end drivers}).
+
+Back end drivers are designed to be close as possible to the
+authentication mechanism.  You can access the additional configuration
+information anywhere from the implementation.

+To get the initial response, you should call the function
+@code{sasl-next-step} with the second argument @code{nil}.
+
+@example
+(setq name (sasl-mechanism-name mechanism))
+@end example
+
+At this point we could send the command which starts a SASL

 * New packages and libraries within Gnus
 
-** The revised Gnus FAQ is included in the manual, *Note Frequently Asked
-Questions::.
-
-** TLS wrapper shipped with Gnus
+** Gnus includes the Emacs Lisp SASL library.
 
-TLS/SSL is now supported in IMAP and NNTP via `tls.el' and GNUTLS.  The
-old TLS/SSL support via (external third party) `ssl.el' and OpenSSL
-still works.
+This provides a clean API to SASL mechanisms from within Emacs.  The
+user visible aspects of this, compared to the earlier situation, include
+support for DIGEST-MD5 and NTLM.   *Note Emacs SASL: (sasl)Top.
 
-** Improved anti-spam features.
+** ManageSieve connections uses the SASL library by default.
 
-Gnus is now able to take out spam from your mail and news streams using
-a wide variety of programs and filter rules.  Among the supported
-methods are RBL blocklists, bogofilter and white/blacklists.  Hooks for
-easy use of external packages such as SpamAssassin and Hashcash are also
-new.  *Note Thwarting Email Spam::.
+The primary change this brings is support for DIGEST-MD5 and NTLM, when
+the server supports it.
 
-** Gnus supports server-side mail filtering using Sieve.
-
-Sieve rules can be added as Group Parameters for groups, and the
-complete Sieve script is generated using `D g' from the Group buffer,
-and then uploaded to the server using `C-c C-l' in the generated Sieve
-buffer.  *Note Sieve Commands::, and the new Sieve manual *Note Top:

-* Changes in group mode
-
-** `gnus-group-read-ephemeral-group' can be called interactively, using `G
-M'.
-
-** Retrieval of charters and control messages
-
-There are new commands for fetching newsgroup charters (`H c') and
-control messages (`H C').
-
-** The new variable `gnus-parameters' can be used to set group parameters.
-
-Earlier this was done only via `G p' (or `G c'), which stored the
-parameters in `~/.newsrc.eld', but via this variable you can enjoy the
-powers of customize, and simplified backups since you set the variable
-in `~/.gnus.el' instead of `~/.newsrc.eld'.  The variable maps regular
-expressions matching group names to group parameters, a'la:
-(setq gnus-parameters
- '(("mail\\..*"
-    (gnus-show-threads nil)
-    (gnus-use-scoring nil))
-   ("^nnimap:\\(foo.bar\\)$"
-    (to-group . "\\1"))))
-
-** Unread count correct in nnimap groups.
-
-The estimated number of unread articles in the group buffer should now
-be correct for nnimap groups.  This is achieved by calling
-`nnimap-fixup-unread-after-getting-new-news' from the
-`gnus-setup-news-hook' (called on startup) and
-`gnus-after-getting-new-news-hook'. (called after getting new mail).  If
-you have modified those variables from the default, you may want to add
-`nnimap-fixup-unread-after-getting-new-news' again.  If you were happy
-with the estimate and want to save some (minimal) time when getting new
-mail, remove the function.
-
-** Group names are treated as UTF-8 by default.
-
-This is supposedly what USEFOR wanted to migrate to.  See
-`gnus-group-name-charset-group-alist' and
-`gnus-group-name-charset-method-alist' for customization.
-
-** `gnus-group-charset-alist' and `gnus-group-ignored-charsets-alist'.
-
-The regexps in these variables are compared with full group names
-instead of real group names in 5.8.  Users who customize these variables
-should change those regexps accordingly.  For example:
-("^han\\>" euc-kr) -> ("\\(^\\|:\\)han\\>" euc-kr)
+** Gnus includes a password cache mechanism in password.el.
 
+It is enabled by default (see `password-cache'), with a short timeout of
+16 seconds (see `password-cache-expiry').  If PGG is used as the PGP
+back end, the PGP passphrase is managed by this mechanism.  Passwords
+for ManageSieve connections are managed by this mechanism, after
+querying the user about whether to do so.
 
 
 * Changes in summary and article mode
 
-** `F' (`gnus-article-followup-with-original') and `R'
-(`gnus-article-reply-with-original') only yank the text in the region if
-the region is active.
-
-** In draft groups, `e' is now bound to `gnus-draft-edit-message'.  Use `B
-w' for `gnus-summary-edit-article' instead.
-
-** Article Buttons
-
-More buttons for URLs, mail addresses, Message-IDs, Info links, man
-pages and Emacs or Gnus related references.  *Note Article Buttons::.
-The variables `gnus-button-*-level' can be used to control the
-appearance of all article buttons.  *Note Article Button Levels::.
-
-** Single-part yenc encoded attachments can be decoded.
-
-** Picons
-
-The picons code has been reimplemented to work in GNU Emacs--some of the
-previous options have been removed or renamed.
-
-Picons are small "personal icons" representing users, domain and
-newsgroups, which can be displayed in the Article buffer.  *Note
-Picons::.
-
-** If the new option `gnus-treat-body-boundary' is non-`nil', a boundary
-line is drawn at the end of the headers.
-
-** Signed article headers (X-PGP-Sig) can be verified with `W p'.
-
-** The Summary Buffer uses an arrow in the fringe to indicate the current
-article.  Use `(setq gnus-summary-display-arrow nil)' to disable it.
-
-** Warn about email replies to news
-
-Do you often find yourself replying to news by email by mistake?  Then
-the new option `gnus-confirm-mail-reply-to-news' is just the thing for
-you.
-
-** If the new option `gnus-summary-display-while-building' is non-`nil',
-the summary buffer is shown and updated as it's being built.
-
-** The new `recent' mark `.' indicates newly arrived messages (as opposed
-to old but unread messages).
-
-** Gnus supports RFC 2369 mailing list headers, and adds a number of
-related commands in mailing list groups.  *Note Mailing List::.
-
-** The Date header can be displayed in a format that can be read aloud in
-English.  *Note Article Date::.
-
-** diffs are automatically highlighted in groups matching
-`mm-uu-diff-groups-regexp'
-
-** Better handling of Microsoft citation styles
-
-Gnus now tries to recognize the mangled header block that some Microsoft
-mailers use to indicate that the rest of the message is a citation, even
-though it is not quoted in any way.  The variable
-`gnus-cite-unsightly-citation-regexp' matches the start of these
-citations.
-
-The new command `W Y f' (`gnus-article-outlook-deuglify-article') allows
-deuglifying broken Outlook (Express) articles.
-
-** `gnus-article-skip-boring'
-
-If you set `gnus-article-skip-boring' to `t', then Gnus will not scroll
-down to show you a page that contains only boring text, which by default
-means cited text and signature.  You can customize what is skippable
-using `gnus-article-boring-faces'.
-
-This feature is especially useful if you read many articles that consist
-of a little new content at the top with a long, untrimmed message cited
-below.
-
-** Smileys (`:-)', `;-)' etc) are now displayed graphically in Emacs too.
-
-Put `(setq gnus-treat-display-smileys nil)' in `~/.gnus.el' to disable
-it.
-
-** Face headers handling.  *Note Face::.
-
-** In the summary buffer, the new command `/ N' inserts new messages and `/
-o' inserts old messages.
-
-** Gnus decodes morse encoded messages if you press `W m'.
+** Gnus now supports sticky article buffers.  Those are article buffers
+that are not reused when you select another article.  *Note Sticky
+Articles::.
 
-** `gnus-summary-line-format'
+** International host names (IDNA) can now be decoded inside article bodies
+using `W i' (`gnus-summary-idna-message').  This requires that GNU Libidn
+(`http://www.gnu.org/software/libidn/') has been installed.
 
-The default value changed to `%U%R%z%I%(%[%4L: %-23,23f%]%) %s\n'.
-Moreover `gnus-extra-headers', `nnmail-extra-headers' and
-`gnus-ignored-from-addresses' changed their default so that the users
-name will be replaced by the recipient's name or the group name posting
-to for NNTP groups.
+** The non-ASCII group names handling has been much improved.  The back
+ends that fully support non-ASCII group names are now `nntp', `nnml',
+and `nnrss'.  Also the agent, the cache, and the marks features work
+with those back ends.  *Note Non-ASCII Group Names::.
 
-** Deleting of attachments.
+** Gnus now displays DNS master files sent as text/dns using dns-mode.
 
-The command `gnus-mime-save-part-and-strip' (bound to `C-o' on MIME
-buttons) saves a part and replaces the part with an external one.
-`gnus-mime-delete-part' (bound to `d' on MIME buttons) removes a part.
-It works only on back ends that support editing.
+** Gnus supports new limiting commands in the Summary buffer: `/ r'
+(`gnus-summary-limit-to-replied') and `/ R'
+(`gnus-summary-limit-to-recipient').  *Note Limiting::.
 
-** `gnus-default-charset'
+** You can now fetch all ticked articles from the server using `Y t'
+(`gnus-summary-insert-ticked-articles').  *Note Summary Generation
+Commands::.
 
-The default value is determined from the `current-language-environment'
-variable, instead of `iso-8859-1'.  Also the `.*' item in
-`gnus-group-charset-alist' is removed.
+** Gnus supports a new sort command in the Summary buffer: `C-c C-s C-t'
+(`gnus-summary-sort-by-recipient').  *Note Summary Sorting::.
 
-** Printing capabilities are enhanced.
+** S/MIME now features LDAP user certificate searches.  You need to
+configure the server in `smime-ldap-host-list'.
 
-Gnus supports Muttprint natively with `O P' from the Summary and Article
-buffers.  Also, each individual MIME part can be printed using `p' on
-the MIME button.
+** URLs inside OpenPGP headers are retrieved and imported to your PGP key
+ring when you click on them.
 
-** Extended format specs.
+** Picons can be displayed right from the textual address, see
+`gnus-picon-style'.  *Note Picons::.
 
-Format spec `%&user-date;' is added into
-`gnus-summary-line-format-alist'.  Also, user defined extended format
-specs are supported.  The extended format specs look like `%u&foo;',
-which invokes function `gnus-user-format-function-FOO'.  Because `&' is
-used as the escape character, old user defined format `%u&' is no longer
-supported.
+** ANSI SGR control sequences can be transformed using `W A'.
 
-** `/ *' (`gnus-summary-limit-include-cached') is rewritten.
+ANSI sequences are used in some Chinese hierarchies for highlighting
+articles (`gnus-article-treat-ansi-sequences').
 
-It was aliased to `Y c' (`gnus-summary-insert-cached-articles').  The
-new function filters out other articles.
+** Gnus now MIME decodes articles even when they lack "MIME-Version" header.
+This changes the default of `gnus-article-loose-mime'.
 
-** Some limiting commands accept a `C-u' prefix to negate the match.
+** `gnus-decay-scores' can be a regexp matching score files.  For example,
+set it to `\\.ADAPT\\'' and only adaptive score files will be decayed.
+ *Note Score Decays::.
 
-If `C-u' is used on subject, author or extra headers, i.e., `/ s', `/
-a', and `/ x' (`gnus-summary-limit-to-{subject,author,extra}')
-respectively, the result will be to display all articles that do not
-match the expression.
+** Strings prefixing to the `To' and `Newsgroup' headers in summary lines
+when using `gnus-ignored-from-addresses' can be customized with
+`gnus-summary-to-prefix' and `gnus-summary-newsgroup-prefix'.  *Note To
+From Newsgroups::.
 
-** Gnus inlines external parts (message/external).
-
-
-
-* Changes in Message mode and related Gnus features
-
-** Delayed articles
-
-You can delay the sending of a message with `C-c C-j' in the Message
-buffer.  The messages are delivered at specified time.  This is useful
-for sending yourself reminders.  *Note Delayed Articles::.
-
-** If the new option `nnml-use-compressed-files' is non-`nil', the nnml
-back end allows compressed message files.
-
-** The new option `gnus-gcc-mark-as-read' automatically marks Gcc articles
-as read.
-
-** Externalizing of attachments
-
-If `gnus-gcc-externalize-attachments' or
-`message-fcc-externalize-attachments' is non-`nil', attach local files
-as external parts.
-
-** The envelope sender address can be customized when using Sendmail.
- *Note Mail Variables: (message)Mail Variables.
-
-** Gnus no longer generate the Sender: header automatically.
-
-Earlier it was generated when the user configurable email address was
-different from the Gnus guessed default user address.  As the guessing
-algorithm is rarely correct these days, and (more controversially) the
-only use of the Sender: header was to check if you are entitled to
-cancel/supersede news (which is now solved by Cancel Locks instead, see
-another entry), generation of the header has been disabled by default.
-See the variables `message-required-headers',
-`message-required-news-headers', and `message-required-mail-headers'.
-
-** Features from third party `message-utils.el' added to `message.el'.
-
-Message now asks if you wish to remove `(was: <old subject>)' from
-subject lines (see `message-subject-trailing-was-query').  `C-c M-m' and
-`C-c M-f' inserts markers indicating included text.  `C-c C-f a' adds a
-X-No-Archive: header.  `C-c C-f x' inserts appropriate headers and a
-note in the body for cross-postings and followups (see the variables
-`message-cross-post-*').
-
-** References and X-Draft-From headers are no longer generated when you
-start composing messages and `message-generate-headers-first' is `nil'.
-
-** Easy inclusion of X-Faces headers.  *Note X-Face::.
-
-** Group Carbon Copy (GCC) quoting
-
-To support groups that contains SPC and other weird characters, groups
-are quoted before they are placed in the Gcc: header.  This means
-variables such as `gnus-message-archive-group' should no longer contain
-quote characters to make groups containing SPC work.  Also, if you are
-using the string `nnml:foo, nnml:bar' (indicating Gcc into two groups)
-you must change it to return the list `("nnml:foo" "nnml:bar")',
-otherwise the Gcc: line will be quoted incorrectly.  Note that returning
-the string `nnml:foo, nnml:bar' was incorrect earlier, it just didn't
-generate any problems since it was inserted directly.
-
-** `message-insinuate-rmail'
-
-Adding `(message-insinuate-rmail)' and `(setq mail-user-agent
-'gnus-user-agent)' in `.emacs' convinces Rmail to compose, reply and
-forward messages in message-mode, where you can enjoy the power of MML.
-
-** `message-minibuffer-local-map'
-
-The line below enables BBDB in resending a message:
-(define-key message-minibuffer-local-map [(tab)]
-  'bbdb-complete-name)
-
-** `gnus-posting-styles'
-
-Add a new format of match like
-((header "to" "larsi.*org")
- (Organization "Somewhere, Inc."))
-The old format like the lines below is obsolete, but still accepted.
-(header "to" "larsi.*org"
-   (Organization "Somewhere, Inc."))
-
-** `message-ignored-news-headers' and `message-ignored-mail-headers'
-
-`X-Draft-From' and `X-Gnus-Agent-Meta-Information' have been added into
-these two variables.  If you customized those, perhaps you need add
-those two headers too.
-
-** Gnus supports the "format=flowed" (RFC 2646) parameter.  On composing
-messages, it is enabled by `use-hard-newlines'.  Decoding format=flowed
-was present but not documented in earlier versions.
+** You can replace MIME parts with external bodies.  See
+`gnus-mime-replace-part' and `gnus-article-replace-part'.  *Note MIME
+Commands::, *note Using MIME::.
 
 ** The option `mm-fill-flowed' can be used to disable treatment of
-"format=flowed" messages.  Also, flowed text is disabled when sending
-inline PGP signed messages.  (New in Gnus 5.10.7)
+format=flowed messages.  Also, flowed text is disabled when sending
+inline PGP signed messages.  *Note Flowed text: (emacs-mime)Flowed text.
+(New in Gnus 5.10.7)
 
-** Gnus supports the generation of RFC 2298 Disposition Notification
-requests.
 
-This is invoked with the `C-c M-n' key binding from message mode.
-
-** Message supports the Importance: (RFC 2156) header.
-
-In the message buffer, `C-c C-f C-i' or `C-c C-u' cycles through the
-valid values.
-
-** Gnus supports Cancel Locks in News.
-
-This means a header `Cancel-Lock' is inserted in news posting.  It is
-used to determine if you wrote an article or not (for canceling and
-superseding).  Gnus generates a random password string the first time
-you post a message, and saves it in your `~/.emacs' using the Custom
-system.  While the variable is called `canlock-password', it is not
-security sensitive data.  Publishing your canlock string on the web will
-not allow anyone to be able to anything she could not already do.  The
-behavior can be changed by customizing `message-insert-canlock'.
+
+* Changes in Message mode
 
-** Gnus supports PGP (RFC 1991/2440), PGP/MIME (RFC 2015/3156) and S/MIME
-(RFC 2630-2633).
+** Gnus now supports the "hashcash" client puzzle anti-spam mechanism.  Use
+`(setq message-generate-hashcash t)' to enable.  *Note Hashcash::.
 
-It needs an external S/MIME and OpenPGP implementation, but no
-additional Lisp libraries.  This add several menu items to the
-Attachments menu, and `C-c RET' key bindings, when composing messages.
-This also obsoletes `gnus-article-hide-pgp-hook'.
+** You can now drag and drop attachments to the Message buffer.  See
+`mml-dnd-protocol-alist' and `mml-dnd-attach-options'.  *Note MIME:
+(message)MIME.
 
-** MML (Mime compose) prefix changed from `M-m' to `C-c C-m'.
+** The option `message-yank-empty-prefix' now controls how empty lines are
+prefixed in cited text.  *Note Insertion Variables: (message)Insertion
+Variables.
 
-This change was made to avoid conflict with the standard binding of
-`back-to-indentation', which is also useful in message mode.
+** Gnus uses narrowing to hide headers in Message buffers.  The
+`References' header is hidden by default.  To make all headers visible,
+use `(setq message-hidden-headers nil)'.  *Note Message Headers:
+(message)Message Headers.
 
-** The default for `message-forward-show-mml' changed to the symbol `best'.
+** You can highlight different levels of citations like in the article
+buffer.  See `gnus-message-highlight-citation'.
 
-The behavior for the `best' value is to show MML (i.e., convert to MIME)
-when appropriate.  MML will not be used when forwarding signed or
-encrypted messages, as the conversion invalidate the digital signature.
+** `auto-fill-mode' is enabled by default in Message mode.  See
+`message-fill-column'.  *Note Message Headers: (message)Various Message
+Variables.
 
-** If `auto-compression-mode' is enabled, attachments are automatically
-decompressed when activated.
+** You can now store signature files in a special directory named
+`message-signature-directory'.
 
-** Support for non-ASCII domain names
+** The option `message-citation-line-format' controls the format of the
+"Whomever writes:" line.  You need to set
+`message-citation-line-function' to
+`message-insert-formated-citation-line' as well.
 
-Message supports non-ASCII domain names in From:, To: and Cc: and will
-query you whether to perform encoding when you try to send a message.
-The variable `message-use-idna' controls this.  Gnus will also decode
-non-ASCII domain names in From:, To: and Cc: when you view a message.
-The variable `gnus-use-idna' controls this.
+
+* Changes in back ends
 
-** You can now drag and drop attachments to the Message buffer.  See
-`mml-dnd-protocol-alist' and `mml-dnd-attach-options'.  *Note MIME:
-(message)MIME.
+** The nntp back end stores article marks in `~/News/marks'.
 
+The directory can be changed using the (customizable) variable
+`nntp-marks-directory', and marks can be disabled using the (back end)
+variable `nntp-marks-is-evil'.  The advantage of this is that you can
+copy `~/News/marks' (using rsync, scp or whatever) to another Gnus
+installation, and it will realize what articles you have read and
+marked.  The data in `~/News/marks' has priority over the same data in
+`~/.newsrc.eld'.
 
-
-* Changes in back ends
+** You can import and export your RSS subscriptions from OPML files.  *Note
+RSS::.
 
-** Gnus can display RSS newsfeeds as a newsgroup.  *Note RSS::.
+** IMAP identity (RFC 2971) is supported.
 
-** The nndoc back end now supports mailman digests and exim bounces.
+By default, Gnus does not send any information about itself, but you can
+customize it using the variable `nnimap-id'.
 
-** Gnus supports Maildir groups.
+** The `nnrss' back end now supports multilingual text.  Non-ASCII group
+names for the `nnrss' groups are also supported.  *Note RSS::.
 
-Gnus includes a new back end `nnmaildir.el'.  *Note Maildir::.
+** Retrieving mail with POP3 is supported over SSL/TLS and with StartTLS.
 
-** The nnml and nnfolder back ends store marks for each groups.
+** The nnml back end allows other compression programs beside `gzip' for
+compressed message files.  *Note Mail Spool::.
 
-This makes it possible to take backup of nnml/nnfolder servers/groups
-separately of `~/.newsrc.eld', while preserving marks.  It also makes it
-possible to share articles and marks between users (without sharing the
-`~/.newsrc.eld' file) within e.g. a department.  It works by storing the
-marks stored in `~/.newsrc.eld' in a per-group file `.marks' (for nnml)
-and `GROUPNAME.mrk' (for nnfolder, named GROUPNAME).  If the
-nnml/nnfolder is moved to another machine, Gnus will automatically use
-the `.marks' or `.mrk' file instead of the information in
-`~/.newsrc.eld'.  The new server variables `nnml-marks-is-evil' and
-`nnfolder-marks-is-evil' can be used to disable this feature.
+** The nnml back end supports group compaction.
 
+This feature, accessible via the functions `gnus-group-compact-group'
+(`G z' in the group buffer) and `gnus-server-compact-server' (`z' in the
+server buffer) renumbers all articles in a group, starting from 1 and
+removing gaps.  As a consequence, you get a correct total article count
+(until messages are deleted again).
 
 
 * Appearance
 
-** The menu bar item (in Group and Summary buffer) named "Misc" has been
-renamed to "Gnus".
-
-** The menu bar item (in Message mode) named "MML" has been renamed to
-"Attachments".  Note that this menu also contains security related
-stuff, like signing and encryption (*note Security: (message)Security.).
-
-** The tool bars have been updated to use GNOME icons in Group, Summary and
-Message mode.  You can also customize the tool bars.  This is a new
-feature in Gnus 5.10.9.  (Only for Emacs, not in XEmacs.)
+** The tool bar has been updated to use GNOME icons.  You can also
+customize the tool bar.  There's no documentation in the manual yet, but
+`M-x customize-apropos RET -tool-bar$' should get you started.  (Only
+for Emacs, not in XEmacs.)
 
 ** The tool bar icons are now (de)activated correctly in the group buffer,
 see the variable `gnus-group-update-tool-bar'.  Its default value
-depends on your Emacs version.  This is a new feature in Gnus 5.10.9.
-
-
-* Miscellaneous changes
+depends on your Emacs version.
 
-** `gnus-agent'
+** You can change the location of XEmacs' toolbars in Gnus buffers.  See
+`gnus-use-toolbar' and `message-use-toolbar'.
 
-The Gnus Agent has seen a major updated and is now enabled by default,
-and all nntp and nnimap servers from `gnus-select-method' and
-`gnus-secondary-select-method' are agentized by default.  Earlier only
-the server in `gnus-select-method' was agentized by the default, and the
-agent was disabled by default.  When the agent is enabled, headers are
-now also retrieved from the Agent cache instead of the back ends when
-possible.  Earlier this only happened in the unplugged state.  You can
-enroll or remove servers with `J a' and `J r' in the server buffer.
-Gnus will not download articles into the Agent cache, unless you
-instruct it to do so, though, by using `J u' or `J s' from the Group
-buffer.  You revert to the old behavior of having the Agent disabled
-with `(setq gnus-agent nil)'.  Note that putting `(gnus-agentize)' in
-`~/.gnus.el' is not needed any more.
 
-** Gnus reads the NOV and articles in the Agent if plugged.
-
-If one reads an article while plugged, and the article already exists in
-the Agent, it won't get downloaded once more.  `(setq gnus-agent-cache
-nil)' reverts to the old behavior.
-
-** Dired integration
-
-`gnus-dired-minor-mode' (see *Note Other modes::) installs key bindings
-in dired buffers to send a file as an attachment, open a file using the
-appropriate mailcap entry, and print a file using the mailcap entry.
-
-** The format spec `%C' for positioning point has changed to `%*'.
+
+* Miscellaneous changes
 
-** `gnus-slave-unplugged'
+** Having edited the select-method for the foreign server in the server
+buffer is immediately reflected to the subscription of the groups which
+use the server in question.  For instance, if you change
+`nntp-via-address' into `bar.example.com' from `foo.example.com', Gnus
+will connect to the news host by way of the intermediate host
+`bar.example.com' from next time.
 
-A new command which starts Gnus offline in slave mode.
+** The `all.SCORE' file can be edited from the group buffer using `W e'.

+
+;;; Commentary:
+
+;; This file implements real bookmarks for Gnus, closely following the way
+;; `bookmark.el' handles bookmarks.  Most of the code comes from
+;; `bookmark.el'.
+;;
+;; Set a Gnus bookmark:
+;; M-x `gnus-bookmark-set' from the summary buffer.
+;;
+;; Jump to a Gnus bookmark:
+;; M-x `gnus-bookmark-jump'.
+;;
+;; Display a list of bookmarks
+;; M-x `gnus-bookmark-bmenu-list'.
+;;
+
+;;; Todo:
+
+;; - add tags to bookmarks
+;; - don't write file each time a bookmark is created
+;; - better annotation interactive buffer
+;; - edit annotation in gnus-bookmark-bmenu
+;; - sort gnus-bookmark-buffer by author/subject/date/group/message-id
+;; - auto-bmk-name customizable format
+;; - renaming bookmarks in gnus-bookmark-bmenu-list
+;; - better (formatted string) display in bmenu-list
+
+;; - Integrate the `gnus-summary-*-bookmark' functionality
+;; - Initialize defcustoms from corresponding `bookmark.el' variables?

-;; How do I Rate an article??
-;;   Before you type n to go to the next article, hit a number from 1-5
-;;   Type r in the summary buffer and you will be prompted.
-;;   Note that when you're in grouplens-minor-mode 'r' masks the

-;; What if, Gasp, I find a bug???
-;; Please type M-x gnus-gl-submit-bug-report.  This will set up a
-;; mail buffer with the  state of variables and buffers that will help
-;; me debug the problem.  A short description up front would help too!

-;; How do I display the prediction for an article:
-;;  If you set the gnus-summary-line-format as shown above, the score
-;;  (prediction) will be shown automatically.

-;; Programmer  Notes
-;; 10/9/95
-;; gnus-scores-articles contains the articles
-;; When scoring is done, the call tree looks something like:
-;; gnus-possibly-score-headers
-;;  ==> gnus-score-headers
-;;      ==> gnus-score-load-file
-;;          ==> get-all-mids  (from the eval form)
-;;
-;; it would be nice to have one that gets called after all the other
-;; headers have been scored.
-;; we may want a variable gnus-grouplens-scale-factor
-;; and gnus-grouplens-offset  this would probably be either -3 or 0
-;; to make the scores centered around zero or not.
-;; Notes 10/12/95
-;; According to Lars, Norse god of gnus, the simple way to insert a
-;; call to an external function is to have a function added to the
-;; variable gnus-score-find-files-function  This new function
-;; gnus-grouplens-score-alist will return a core alist that
-;; has (("message-id" ("<message-id-xxxx>" score) ("<message-id-xxxy>" score))
-;; This seems like it would be pretty inefficient, though workable.

+;;; Commentary:
+
+;; This library is a direct translation of the Samba release 2.2.0
+;; implementation of Windows NT and LanManager compatible password
+;; encryption.
+;; 
+;; Interface functions:
+;; 
+;; ntlm-build-auth-request
+;;   This will return a binary string, which should be used in the
+;;   base64 encoded form and it is the caller's responsibility to encode
+;;   the returned string with base64.
+;;
+;; ntlm-build-auth-response
+;;   It is the caller's responsibility to pass a base64 decoded string
+;;   (which will be a binary string) as the first argument and to
+;;   encode the returned string with base64.  The second argument user
+;;   should be given in user@domain format.
+;; 
+;; ntlm-get-password-hashes
+;;
+;;
+;; NTLM authentication procedure example:
+;;
+;;  1. Open a network connection to the Exchange server at the IMAP port (143)
+;;  2. Receive an opening message such as:
+;;     "* OK Microsoft Exchange IMAP4rev1 server version 5.5.2653.7 (XXXX) ready"
+;;  3. Ask for IMAP server capability by sending "NNN capability"
+;;  4. Receive a capability message such as:
+;;     "* CAPABILITY IMAP4 IMAP4rev1 IDLE LITERAL+ LOGIN-REFERRALS MAILBOX-REFERRALS NAMESPACE AUTH=NTLM"
+;;  5. Ask for NTLM authentication by sending a string
+;;     "NNN authenticate ntlm"
+;;  6. Receive continuation acknowledgment "+"
+;;  7. Send NTLM authentication request generated by 'ntlm-build-auth-request
+;;  8. Receive NTLM challenge string following acknowledgment "+"
+;;  9. Generate response to challenge by 'ntlm-build-auth-response
+;;     (here two hash function values of the user password are encrypted)
+;; 10. Receive authentication completion message such as
